I’ve been setting up a new Proxmox server and messing around with VMs, and wanted to know what kind of useful commands I’m missing out on. Bonus points for a little explainer.

Journalctl | grep -C 10 'foo' was useful for me when I needed to troubleshoot some fstab mount fuckery on boot. It pipes Journalctl (boot logs) into grep to find ‘foo’, and prints 10 lines before and after each instance of ‘foo’.

    To add to this one, it also supports more than just the previous command (which is what !! means), you can do like sudo !453 to run command 453 from your history, also supports relative like !-5. You can also use without sudo if you want which is handy to do things like !ls for the last ls command etc. Okay one more, you can add :p to the end to print the command before running it just in case like !systemctl:p which can be handy!
